Center Neck Boiling Flask Thermowell, 24/40
A thermowell is a device to reduce the risk of leaks while taking temperature readings. It is basically a long glass tube which is sealed on one end and partially filled with a fluid to transfer heat such as mineral oil. A thermometer is inserted into the tube and the sealed end would typically be immersed in the contents of a boiling flask which transfer heat to the thermometer and allow temperature readings to be taken. The opposite end has a female 24/40 joint for an air tight and dependable seal.
Note: the length of the thermowell is fixed and must be matched to the specifications of the boiling flask. If you'd like us to make a custom thermowell for you, contact us with your preferred joint size and measurements.
